Star Death: Crab Nebula
Remains of an exploded star Full Story Below
Star Death: Crab NebulaMany of the atoms in your body formed billions of years ago, inside an aging star.
Some stars die slowly, giving off puffs of gas and dust before collapsing to form small white dwarf stars. Much larger stars die suddenly in powerful explosions known as supernovae, blasting gas, dust, and energy out in all directions as they collapse to form tiny neutron stars or black holes. The gas and dust expelled by dying stars eventually combines with the remains of others to form new stars, planets, and moons.
The Crab Nebula is a supernova remnant: the remains of star whose life ended in a supernova explosion. Observing the different types of light given off by the supernova remnants like the Crab Nebula allows us to better understand what happens to massive stars at the end of their lives; to understand what has happened to the matter and energy that made up the star; and better understand where the planets, moons, rock, water, soil—and living things—originally come from.
Quick Facts: Crab NebulaAlso known as: Messier 1 (M1)
Type of Object: Supernova Remnant
Distance from Earth: 6,500 light-years
Size: Approximately 10 light-years across
Location in the Sky: Taurus Constellation
Location in the Universe: Milky Way Galaxy, outside the Solar System
Did You Know: The bright light from the supernova explosion that formed the Crab Nebula was observed by Chinese, Japanese, and Arab astronomers in 1054 A.D. The light has since faded and the Crab Nebula is no longer visible without a telescope.
